I like the idea, it's a promising puzzle game and I like the smooth looking visuals. However, there are a couple of things that are quite disrupting the experience:
- The controls feel very strange. It's hard to navigate with QEZC and arrow keys are probably mapped wrong.
- The white cube looks very similar to the player cube. Combined with the rather strange "push" animation this disorients the player a lot. It really took us a while to figure out what is actually happening when white cube is pushed.
- It seems that only a very small damage already prevents pushing of the black cube. I did not find any indicator that would tell if I can or can not push it, which makes the playthrough a bit try & see. Especially since the temperature/health/damage is UpdateLoop-based while controls are Turn-based.
Overall good job on making a game, good luck and keep making!
